Ezekiel 40:16, 25

The alcoves and the projecting walls inside the gateway were surmounted by narrow parapet openings all around, as was the portico; the openings all around faced inward. The faces of the projecting walls were decorated with palm trees.

The gateway and its portico had narrow openings all around, like the openings of the others. It was fifty cubits long and twenty-five cubits wide.
